Patented Nov. 23, 1937 UNITED STATES HATCH CONSTRUCTION Charles David Bonsall, Pittsburgh, Pa., assignorl to P. H. Murphy Company, New Kensington, Pa., a corporation of Pennsylvania Application July 25, 1935, Serial No. 33,041 Renewed May 11, 1936 12 Claims.

This invention relates to the hatchway construction of a car roof. It has for its principal objects to produce a strong and durable weatherproof hatchway construction of simple and economical construction. The invention consists in the hatchway construction and in the combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawings, which form part of this specification and wherein like symbols refer to like parts wherever they occur,

Fig. 1 is a plan View ofthe end portion of a metal car roof provided on each side of the ridge with a hatchway construction embodying my invention,

Fig. 2 is a vertical section through one of the hatchways, the section being taken transversely of the roof on the line 2 2 of Fig. 1,

Fig. 3 is a vertical section through said hatchway, the section being taken longitudinally of the roof on the line 3-3 of Fig. 1,

Fig. 4 is a fragmentary plan View of the roof in the region of said hatchway, with parts shown broken away,

Fig. 5 is a vertical section through the hatch sheet of the roof on the line 3 3 in Fig. l,

Fig. 6 is a plan view of the metal hatch frame or hopper member of said hatchway; and

Fig. 7 is a view of said frame partly in side elevation and partly in vertical cross-section.

Referring to the accompanying drawings, my invention is shown in connection with a refrigerator car equipped with a metal car roof comprising self-supporting sheets I of' rolled steel that span from side -plate 2 to side plate 2 of the car and have their ends rigidly secured to the sloping top flanges of eaves angle strips 3 whose vertical anges are secured to the outer faces of said side plates and cover the. upper end of side The rooishects are provided along their adjacent margins with upstanding flanges 5 that are straddled by seam caps 5a that are riveted to said flanges and to the eaves angle strips 3. The roof sheets have depending eaves anges 6 that overhang the upper end of side fascia boards I that are secured to the side sheathing with their tops substantially flush with the tops of the respective side plates. At the end of the car the end roof sheet is secured to the outstand- 5`) ing upper flange of an end angle strip 8 whose vertical ange is bolted to the outer face of the end plate 9 of the car and covers the upper end of the end sheathing I0. The end fascia board II is secured to the outer face of the end sheath- 5:, ing; and the outer margin of said end sheet has a depending ange I2- that overhangs said end fascia board. The car is provided with suitable insulation I3; and a suitable insulating lining I4 is suspended from the carlines I5 of the car.

One of the roof sheets, hereinafter referred to as a hatch sheet, has one or two hatchway openings Which lead into the ice bunker of the car. The hatchway opening is a square-cornered opening I6 located in the top of an upstanding boss lI'I that is pressed in the hatch sheet. In the construction illustrated, the hatchway opening is defined by a wooden hatch frame I8 supported between and extending above adjacent carlines I5 and provided above said carlines and the general plane of the roof with a round-cornered wooden edge frame I9 whose outer sides slop downwardly and outwardly. The raised boss I1 in the hatch sheet is shaped to snugly lit the edge frame I9 of the wooden hatch frame I8; that is, said boss is provided with rounded corners and its side wall slopes downwardly and outwardly' to conform to the shape of said edge frame.

The wooden hatch frame is provided with a sheet metal flashing or liner 2l! whose upper end is flanged outwardly, as at 2|, betWeen'the upper edge of said frame and the underside of the boss I'I in the hatch sheet. The lower end of said liner is preferably flanged outwardly, as at 22, beneath the insulating lining I Il. Located in the upper end of the liner or flashing is a strong and rigid hopper member or hatchway frame 23 of metal that is provided at its top with a ange 24 that extends outwardly over the top of the hatch sheet boss I1 and thence downwardly over the sloping side walls thereof. The metal hatch frame 23 snugly fits the metal hatch liner 20 and the boss Il of the hatch sheet and has its sides converging downwardly to constitutea seat for a closure in the form of a tapered wooden plug 25 of the type commonly used for closing the hatchway openings. The upper portions of the wooden'hatch frame YI 8 and the metal liner 20 therefor are also beveled to conform to the downwardly converging walls of the metal hatch frame 23. 'I'he wooden plug is carried by a metal cover 26 which is preferably secured by a hinge 21 to an adjacent seam cap 5a. The margins 28 of the metal cover slope downwardly and outwardly to conform to the slope of the boss engaging top flange 24 of the metal hatch frame 23.

'I'he hereinbefore described hatch construction has several advantages. The boss in the hatch sheet snugly nts the beveled and round-cornered wooden hatch frame and the hatch opening is located in the top of said sheet above the drainage level thereof. The metal hatch lining serves as a weatherproong flashing for the opening in the wooden hatchfframe. The metal hatch frame provides a square-cornered seat for the squarecornered hatch plug; it also serves to'reinforce the hatch sheet boss and the wooden hatch frame and to hold the hatch sheet down on the car; and it also alords a suitable support for the ice in course of loading and protects the upper portions of the hatch lining and the hatch sheet boss from being damaged.
